open channel flowmeter, ultrasonic flow meters for river volumetric flow measurement, irrigation tunnel



The ultrasonic flowmeters are commonly applied to measure the velocity of liquids that allow ultrasonic waves to pass, such as water, molten sulfur, cryogenic liquids, and chemicals. Transit time designs are also available to measure gas and vapor flow. Be careful because fluids that do not pass ultrasonic energy, such as many types of slurry, limit the penetration of ultrasonic waves into the fluid. In Doppler ultrasonic flowmeters, opaque fluids can limit ultrasonic wave penetration too near the pipe wall, which can degrade accuracy and/or cause the flowmeter to fail to measure. Transit time ultrasonic flowmeters can fail to operate when an opaque fluid weakens the ultrasonic wave to such an extent that the wave does not reach the receiver.


The main function characteristics:

  •  With a fully independent intellectual property rights.
  •  Has wide range of temperature compensation and original ERD interference intelligent identification system, measurement data stability, high precision.
  •  Six groups flow condition all data sending 485 serial ports output, PC directly receive, decimal shows, the convenient user record and read archived.
  •  Original "fluid flow correction system" that flow coefficient according to slot size and level to be automatic operation weir and timing compensation.
  •  The blackout time time, the year/month/day/when/points/SEC, flow data, using the ferroelectric double backup storage 10 years off.
  •  Original "measuring tank jam recognition alarm system" can detect liquid slag quality measurement slot throat and obstruction caused by measurement.
  •  Precise date determined when the calendar clock Settings, display and cooperate with the memo and time axis to file information records.
  •  Has 4~20 mA three wire system, RS485, switch quantity and so on many kinds of signal output function selection.
  •  Using intelligent measuring high, digital calibration, the user installation calibration simple and quick.
  •  The ultrasonic non-contact measurement with no moving parts, flow without components within, no block sensor fault hidden trouble.

How to use

The velocity of the solid particles in slurry can be different than its liquid carrier fluid. Be careful applying ultrasonic technology when the solid particles can become concentrated in one part of the flowing stream, such as in a horizontal pipe flowing at a relatively low velocity. Be careful when applying Doppler ultrasonic flowmeters in slurry applications because the solid particles can produce strong signals that can cause the Doppler flowmeter to measure the velocity of the solids and not the velocity of the liquid.

For transit time ultrasonic flowmeters, be sure that the fluid can adequately conduct ultrasonic waves, because the flowmeter will not measure when the ultrasonic waves cannot penetrate the flow stream between the transducers. Similarly, ultrasonic waves must be able to penetrate the fluid for Doppler flowmeters to operate accurately. When the fluid is relatively opaque and does not penetrate the fluid, Doppler flowmeters tend to measure the velocity of the fluid at or near the pipe wall, which can cause significant measurement error and/or cause the flowmeter to fail.
